Alright thanks guys, I think I will check the CG again and probably take away some weight.
I didn't think that it was tail heavy because it went up, but because it also rolled very fast, aswell as went up.
My instructor made it roll slower with expo (I think that's what it is called). Now its like my old LT 40, other than the fact that it lands fast. (I wish I bought a 5 or 6 channel rx for flaps)
